Critical Mozilla Firefox Zero-Day Allows Code Execution


The bug is already being exploited in the wild, but Firefox has provided patches for those who may be vulnerable.



Mozilla
has patched a critical security vulnerability in its Firefox Web browser thats being actively exploited in the wild.
Tracked as CVE-2024-9680, the vulnerability is a use-after-free issue in Animation timelines, with attackers exploiting it to execute arbitrary code,
according to Mozillas advisory
. It carries a CVSSv3 vulnerability-severity rating of 9.8 out of 10 and a low attack complexity (no privileges or user interaction is needed to successfully exploit the flaw), and translates into high risk in the event of a successful attack.
Critical bugs in Firefox, which is used by around
178 million people
worldwide, are few and far between. The Web browser hasnt had to offer patches for such a severe flaw since March, and only a small number have been discovered in the past few years.
The disclosure sparked a flurry of alerts from international cyber agencies, including
Dutch national cyber center
Nationaal Cyber Security Centrum, and the cybersecurity centers of Canada and Italy.
The
Web browser vulnerability
affects Firefox 131.0.2, Firefox ESR 128.3.1, and Firefox ESR 115.16.1. Users should upgrade to version 131.0.2 in Firefox and to versions 115.16.1 or 128.3.1 for Firefox ESR to fix the vulnerability and thwart potential exploitation.
